TELESCOPE MOUNTING FOR RIFLES Filed Oct. 23. 1951 Patented July 21,1953

UNHTED 2 Claims.

This invention relates to mountings as applied to hunting or targetrifles, and the like, for the functional support of telescopes as usedto aid in sighting on distant objects. More particularly the inventionhas reference to mountings that are designed for the reception andsupport of telescopes with end enlargements that prevent the endwiseapplication of the telescope to its supports as is sometimes the case.

It is the principal object of the present invention to provide novelmountings of the above character that can be so applied to the gun asnot to interfere with sighting an object.

It is also an object of the invention to provide mountings that areattached to a side plate, and which plate can be readily detached fromthe gun if such is desired, and will thereby bodily remove the mountingsand telescope from the gun.

Yet another object is to provide mounting blocks that are adapted to beattached to a side plate, and are formed at the side opposite the platewith recesses designed to receive the barrel portion of the telescopetherein.

Yet another object of .the invention resides in the details ofconstruction of a novel form of front end sight for the gun.

Still further objects reside in the details of construction andcombination of parts embodied in the mountings for the telescope, andthe use therewith of a rear peep sight and an illuminated front endsight.

In accomplishing these and other objects of the invention, I haveprovided the improved details of construction, the preferred forms ofwhich are illustrated in the accompanying drawings, wherem Fig. l is aside view of a gun equipped with telescope mountings embodied by thepresent invention; and a telescope applied thereto.

Fig. 2 is a top view of the same parts.

Fig. 6 is a side view, partly in section of the illuminated sightmounting screw.

Fig. 7 is a cross-section taken on line in Fig. 5.

Referring more in detail to the drawings- In Figs. 1 and 2, I have showna portion of a gun to which the present telescope mounting means hasbeen applied. A portion of the gun frame is designated by numeral I andin this frame the breach portion of the gun barrel [3 is is a flat,vertical plate [5 which is fixedly secured to the frame by a pluralityof bolts and screws I6 shown in dotted lines in Figs. 1 and 2. The platel5 extends substantially above the level of the frame and breach portionof the barrel, as well shown in Figs. 1 and 3.

Fixed to the plate l5 adjacent its forward and rearward ends, are thetelescope mountings of this invention, which are designated in theirentireties by reference niunerals l8 and [8. Each is like the other and,therefore, in the following description, mounting I8 will be describedin detail, with the understanding that the description applies equallyto both mountings.

As best shown in Figs. 3 and 4, the mounting l8 comprises a rectangularblock of metal, such as aluminumor other suitable material, that isdisposed with one end flatly engaged against the inside surface of theplate I5 as shown in Fig. 3, and secured thereto by means of screws 2|.The block is formed with a large round hole 22 there-- through. Thishole is directly above and axially parallel with the gun barrel. At oneside of the hole 22, the metal of the block is out free as indicated bythe lines 24-44 in Figs. 1 and 3, and this detached portion of theblock, designated by reference numeral 20x, is normally secured in itsoriginal position by screws 25 that are applied vertically through topand bottom portions of the block, as seen in Fig. 3.

The blocks I8-l8 are supported by the plate 15 somewhat spaced above theframe I0, thus providing open spaces, as at 26-26 in Fig. 1, betweenthem and the frame for normal sighting of the gun by use of the rearsight 2! seen in Fig. 1, and the front end sight 28, shown only in Fig.5, and later described in detail.

Located within the hole 22 of the block and coaxially thereof, is ashort cylindrical collar or band made up of two complementalsemi-circular segments 3I-3|. The outside diameter of the collar issomewhat lesser than the diameter of the hole 22 that contains it, thusto provide for lateral adjustment of the collar in the block for thealigning of the telescope, as is presently explained.

It is shown in Fig. 3 that each segment of the collar is supported bytwo pivot like supports mounted in the block and extended into the hole22, at 90 spacing. One of the supports comprises an adjusting screw thatis adjustably threaded through the block wall and which has a conicallytapered inner end portion seated in a V-shaped channel 42 that is formedin the outer surface of the segment in its circumferential direction.The screw has a knurled head 401' at its outer end whereby it can beinwardly or outwardly adjusted, and a spring clip 43 on the blockengages yieldingly with the head 40a: to retain any adjustment of thescrew that has been made.

The other support comprises a stud 45 that is slidably fitted in a hole46 formed in the block. The stud has a conically tapered inner endportion 45 engaging in a V-shaped channel 42 formed in the segment in adirection circumferentially of the collar. The stud has an encirclingfiange 41 and this bears against a rubber cushion 48 seated in a socket48 that opens to the hole 46. In the disposition of the four pivotmembers, as shown in Fig. 3, it is to be noted that each screw 40 isdirectly opposite one of the yieldably mounted studs 45.

The telescope 50 is contained in the two mountings within the twocollars, each comprised by the semi-circular segments 3l-3|'; thesebeing fitted closely to the telescope barrel as indicated in dottedlines in Fig. 3.

To apply the telescope 50 to the mountings [8-18; and functionallysecure it, the side portions 2090 of the blocks are first removed. Thesegmental bands ilk-3! are then fitted to the telescope, at properspacing and the assembly is then laid in the holes of the blocks throughtheir open sides. Then the removed side portions 20:1: of the blocks arereplaced and secured by the screws 25. In this assembling, the pivotlikesupports 40 and 45 are caused to be seated in the V-shaped channels42-42 of the two segments, as has been clearly shown in Fig. 3. Finallythe screw supports 40 are adjusted inwardly or outwardly as required tobring the telescope in exact alignment with the barrel.

It has been shown in Fig. 4 that the segmental collar is cylindrical andof lesser length than the hole 22 of the block containing it, and thatit is located centrally of the hole. To aid the supporting members 4045in keeping the collar in this position, pins are passed verticallythrough the block, to engage with opposite ends of the collar atopposite sides of the contained telescope barrel, as best shown in Fig.4. These pins are threaded at their lower ends for their fixedsecurement.

'FOr ordinary sighting, the gun sights 27 and 28 can be used in theusual way. For accurate sighting, a peep sight plate 10 is attached tothe lower edge portion of the rear block to extend downwardly therefrom.This has a substantial open space H across which is a web 12 containinga peep hole 73.

At the front end of the barrel is the sight 28 shown in Figs. 5, 6 and7. This comprises a vertical lug 78 mounted on a cross bar 19 that has aclove tailed fit in a cross channel 80 in a rib 8! formed along the endof the barrel.

Threaded into the lug, at its inner end is a screw 82 with head 83formed with face depression 83' containing a luminous substance 84 thatis readily seen when sighting through the peep hole of the plate 70.

With the mountings so formed, a telescope of the character shown, withend enlargements, can be easily and readily applied. After being mountedit can be left in place and will not interfere with normal sighting byuse of the gun sights.

The device can be bodily removed by detachment of the plate l5.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is
